Pass XP-17 and Hana ML loading question

SSG, when you say you hear hiss at “above 70db”, are you talking Soind Pressure Level (SPL) or voltage? If SPL, bow are you measuring that? 70 db SPL at the listener position is not very loud. Anyway, hiss when you crank the volume control on a solid state preamplifier is usually a sign it’s gain is inadequate for the input signal voltage OR RFI.

static is generated somewhere between cartridge and Preamp I can't figure out if its is inner generated or pick from some kind of electric fields generated by what I suspect TV hanging above.

@ssg308 By static do you mean a crackling sound? One cause of this is a platter pad that has a high tendency to produce static electricity, such as one made from felt (which should only be used for DJ use and not in a home stereo as they have no sonic benefit).

You might also have a bad ground; a bad connection, the platter not grounded or the arm not grounded.

Normal line noise sounds like low background noise that you can hear when switching from let say CD input to Phono, and I get that one but  when table is connected to preamp normal line noice is covered with slightly higher pitch static like sound.
